MAINTENANCE
2. LUBRICATION -- GEAR HOUSING
a. The Gear Housing has been pre-lubricated at
the factory; however, the grease level should
be checked as follows using SAE 90 out-
board motor grease. (See Figure 2).
(f) Prior to initial operation.
(2) After first four (4) hours of use.
f3) Recheck after every fifty (50) hours
running tame.
(4) Replace with new lubricant at the end
of your outboard motor season. This
is =mportant, as it removes any water
from the gear housing and prevents
possible corrosion tO intern!l parts.
b. To Check, Drain or Fill gear housing, follow
these steps:
{1) Position outboard motor upright.
{2) Remove drain plug and washer, then
insert nozzle of gear lubricant tube
into hole.
(:3) Squeeze tube until lubricant is forced
out around tube.
(4) Replace plug end washer. Be sure plug
is tightened securely.
(5) To achieve complete drainage of lubri-
cant, remove cotter pro, propeller and
shear pin from propeller shaft, also,
gear housing cover by unscrewing 2
bolts.
(6) When lubrMcant has comptetelydrained.
replace parts and refill gear housing
using filling procedure above.
c. For best results, lubricate propeller shaft
with lithium grease every 30 to 60 days.
3. MUFFLER INSPECTION
a. Periodically remove muffler cover by un-
screwing screws and inspect for carbon
build-up inside the muffler inlet and outlet,
the exhaust port and the combustion
chamber of the cylinder, Excessive carbon
will prevent drawing the maximum power
out of the engine. (See Figure 3).
b. Care should be exercised while cleaning
away carbon to prevent scratches to the
surface of the engine components and drop-
ping carbon inside of crankcase.
4. PROLONGED STORAGE
a. To store your outboard motor for pro-
longed storage, prepare outboard as fol-
lows:
(1) See paragraph on stopping procedures.
tRef. 10)
(21 When removing outboard motor from
boat, allow all water to drain from
unit.
b.
c.
(3) The outboard motor should b_
mounted on astand vertically with
power head up for storage.
(4) Pull starter handle _lowty until resist-
ance is felt due to compression pres-
sure. then stop. Release starter tension
SlOWly tO prevent engine from revers-
ing rotation due to compression
pressure. This positlon will close both
the intake and exhaust ports for
storage.
(5) Drain and fill gear housing as outlined
under Lubrication of Gear Housing.
(Ref. 2)
{6) Wipe exterior completely with fresh
water cloth and then apply light coat-
ing of oil.
When starting a new season, always use fresh
gasoline. Last year's gasoline may have
varnish deposits that will plug the carbu*
retor jets, thus requiring a complete over-
haul.
To plan for the coming season, we recom-
mend you contact your Sears Service
Center before the new season for any service
repair work required.
OPERATION
5. NEW AUTOMATIC CLUTCH
a. New automatic clutch. Based on adual
centrifugal clutch design, it allows the outJ
board prop to turn at very slow speeds or
even come to a complete stop while the
engine continues operating efficiently. It
eliminates the need to shift gears by hand
and prevents the engine from overheating
and stalling at slow speeds.
When engine starts, motor is neutral. As
throttle increases, sub clutch engages= At
appx. 6 MPH, main clutch engages to
provide direct drive for crmsing.
